Input-output and the firm: Some comments

Morrison W. I. (1973) Input-output and the firm: Some comments, Reg. Studies 7, 253–256. This paper continues the debate started by Tiebout and continued recently in Regional Studies by Hewings and Greytak, who both suggested that a method originally proposed by Tiebout could be used to integrate an individual firm into a regional input-output table. Tiebout's approach is considered in some detail, and a number of critical comments are made. It is shown that Tiebout's method was not intended for use in the way Hewings intimated, and, consequently, many of Greytak's criticisms become less important. Finally, it is suggested that an iterative approach to the Leontief inverse is often most suitable in impact studies.
